I immediately thought of this scripture you posted concerning who killed Jesus.....and it also seems that....
1. The Jews delivered him to be killed at the result of a sham trial that broke their own laws...
2. The Romans also killed him as Pilate gave the death sentence and Roman Soldiers nailed him to the cross after a good ole beat down........
3. The Heavenly Father desired his death as well so as to fulfill His will...
4. Jesus wanting to please the Father laid down his life willingly...
5. Technically Adam is guilty as well, had he not sinned...
6. EVE...Well that's another story..Had she had her head on straight when the serpent.....
7--->number of completion....Humanity over all is guilty as well as Christ did pay humanities sin debt.
And on and on and on.......
